朋友用他的信用卡幫我在hotel.com 訂了日本的飯店 （APA hotel) 已經付清款項 入住人是填我 請問如果我朋友沒去 這樣會有什麼問題嗎！

what's guest list when you booked hotel? your friend need to change list (call hotel) if he/she is not there when checkin. you can use your credit card when checkin if nothing had been paid.

The guest list is my name. All the payment have been paid. I just worry about they want to check credit card again

沒遇過入住檢查信用卡。 但建議列印入住憑證帶去（或至少手機能出示入住憑證） 住房人是你的名字，不會有什麼問題。
